的有由登光管與以螢光管照射之光作為表面光源之導光體 所構成之導光體方式者。然而，由於該導光體方式需要可 得到均-之表面發光之程度之厚度（大約是液晶晶胞之3 15倍），因此，不易使液晶顯示裝置整體之厚度薄化。 因此’近年來，盛行嘗試使用表面發光元件光源作為 背光。特別是表面發光元件使时機EL元件所構成之有機 EL照明裝置，因為可非常薄，因此具有作為液晶顯示裝置 之背光之實力。 20 帛9圖係顯示習知有機EL照«置之一構成例之概略 截面圖。 該有機EL照明裝置，係於由玻璃等構成之透明基板1〇1 上形成由ITO等透明電極構成之陽極102，再於其上依序積 層含有有機發光體之有機EL層、與由Li、Mg、义等功函數 1251700 小之金屬構成之陰極104，且，為了阻隔水分或氧等外氣， 使用黏著劑106使由玻璃等構成之密封板1〇5於乾燥氮氣環 境下黏著並密封透明基板1〇1。使用如前述之有機EL照明裝 置作為液晶顯示裝置之背光時，背光可薄化，且液晶顯示 5裝置全體之厚度亦可缚化。 然而，近年來，液晶顯示裝置更大面積化之需求高漲， 为光之有機EL照明裝置亦必須大面積化。然而，隨著有機 EL照明裝置之大面積化，不能漠視電極阻抗之影響。特別 是使用於陽極之透明電極之汀〇等非金屬材料之電阻率 10低，因此，電壓降低之影響大，會有有機EL照明裝置形成 發光不均或透明電極中之發熱增加之問題產生。 為了解決前述問題，必需使透明電極之電阻值降低。 因而有專利文獻1所揭示之使用由金屬構成之低電阻之輔 助電極藉此降低透明電極之電阻之技術。然而，因為金屬 15於可見光域具有不透光性，因此，輔助電極部會遮蔽有機 EL照明裝置之發光而使亮度降低。 解決如則迷之問題之方法揭示於專利文獻2。該方法係 於液晶顯示裝置之顯示像素電極之形成領域以外之部位， 即不直接影響顯示之部位設置輔助電極。藉該結構，由於 20液晶顯示裝置原本就是在不透光之部位設置輔助電極，因 此，由液晶顯示裝置整體來看，係實質地解決了辅助電極 遮光所造成之亮度降低問題。 然而，即使是於專利文獻2所揭示之結構中，在輔助電 極上之不透光部位中之有機EL層仍有電流流動，會使有機 1251700 EL照明裝置之發光效率降低。又，由於金屬材料之表面平 坦性通Ό父ITO差’因此，會成為輔助電極與陰極間發生短 路或兩者間產生漏電流之原因。 專利文獻1專利公開公報第200心268982號 5 專利文獻2專利公開公報第2002-156633號 本發明係鑒於前述課題作成者，且本發明之目的在於 提供-種提昇械EL照明裝置之發級率並實現低消耗電 力=具有可防止伽電極與第2電_產生短路或漏電流

液晶層17。第1透明基板13係由玻璃等構成，並於表面形成 有由ΙΤ〇等構成之條紋狀之透明電極11，且於透明電極11 上形成有配向膜12者。第2透明基板16係由玻璃等構成，並 1251700 於表面形成有與由ITO等構成之透明電極u垂直之多數條 、、文狀之透明電極14，且於透明電極14上形成有配向膜15 者。4述液晶層17係由使配向膜12、15對向之第丨透明基板 13與第2透明基板16挾持。又，於第〗透明基板13之裡面配 置有偏光板18，並於第2透明基板16之裡面配置有偏光板 19。该液晶晶胞2，係如第丨八圖、第1B圖所示般藉由使透 明電極11與透明f極14垂直，由隔著兩者之液晶層17等重 受之形成矩陣狀之部分構成多數顯示像素電極⑽口部）1〇。 10 15 20 此外，液sa晶胞於本文中係單純以矩陣型記述，然而 本毛明之結構亦可適用於像素部設有薄膜電晶體(tft)等 轉換元件之主動矩陣型之液晶晶胞。 有機此照明裝置3之結構，係如第2圖所示般於由玻璃 等構成之第3透明基板21之表面形成由IT〇等構成之透明電 極之陽極22，㈣極22上形賴助電㈣之圖案，並形成 絕緣膜24使其覆蓋輔助電極2让面，並且於陽極22上依序 形成有機EL層25及金屬電極之陰極％以覆蓋辅助電極及 、、、巴緣膜24

25以覆蓋辅助電極23。 由於有機EL層25係於挾持其之陽極22與陰極％之間施 1〇加電壓，因此，第3圖中輔助電極23之上面透過有機此層乃 與陰極26之間之導通係有機EL照明裝置3之發光效率降低 之主要原因。因此，如本實施形態般，於辅助電極Μ之上 面形成絕緣膜24以使辅助電極23之上面與有機EIJ|2y€ 緣，藉此可提升有機EL照明裝置3之發光效率。 15 且，第3圖之情況下，金屬材料之平坦性不佳會有使輔 助電極23與陰極26之間產生短路或漏電流之虞。本實施形 態於輔助電極23之上面形成絕緣膜24，藉此使輔助電極幻 與陰極26之間隔著絕緣膜24確實地絕緣，防止前述短路或 漏電流。 0 有機EL層25有由陽極22側起為電洞輸送層/有機發光 層之2層結構、或電洞輸送層/有機發光層/電子輸送層之3 層結構、或電洞注入層/電洞輸送層/有機發光層/電子輪送 層之4層結構等。例如，有使用a-NpD作為電洞輸送層， 且以Alq作為有機發光層之2層結構之有機。該結構之 12 1251700 元件係付到綠色之發光 各種發光色之摻雜物， 件。 。又，藉由在有機發光層添加具有 可形成具有各種發光色之有機EL元 5 10 物二Γ機發光層添加分細^、枚之摻雜 ^ ’或積層添加有分別發R、G、B光之摻雜物 層，可得到發白色光之有機EL元件。 陰極26為了要有效率地注入電子於有機扯層25,係以 功函數小之料驗金屬及氟化料鹼金屬化合物為材料作 、^而&於驗金屬等功函數小之金屬不穩定，因此 為了要穩定化’要同時使用銘或銀等穩定金屬。例如，使 用銘鐘σ m、氟化鐘/!g2層結構作為陰極％。 密封板28係以玻璃等作為材料，且，為了要使有_L 層25與外氣隔絕’係藉例如環氧樹㈣黏著劑於氮氣環境 下與第3透明基板21黏著並密封。 15 20 如第1C圖所不’重疊液晶晶胞2與有機EL照明裝 置3 ’使液晶晶胞2之偏光板18與有機EL照明裝置3之第3透 明基板21對向’且如第1A圖、第_所示般於顯示像素電 極10之非形成領域之配置成矩陣狀之顯示像素電㈣間重 疊格子狀之1«助電勘使其位於位置—致處，而構成液晶 顯示裝置1。 (液晶顯示裳置之製造方法） 第4A圖第4F圖係依步驟順序顯示前述本實施形態之 液晶顯示裝置之製造方法之概略截面圖。於此，主要係針 對本灵施开八、之液晶顯不裝置之主要結構之有機el照明裝 13 1251700 置之製造步驟作說明。 首先，如第4A圖所示，於由玻璃等構成之第3透明基板 21上形成由ιτο等構成之陽極22,並於陽極22上形成例如鋁 (A1)膜31作為電極材料後，塗布形成感光性樹脂材料之聚醯 5 亞胺32之膜。 接著’如第4B圖所示般藉微影成像法使聚醯亞胺膜32 曝光並顯像，並加工聚醯亞胺膜32形成絕緣膜24之圖案。 接著，如第4C圖所示般以絕緣膜24作為掩模對八丨膜31 乾姓刻，藉此形成仿照絕緣膜24之形狀之輔助電極23之圖 1〇案。此時，輔助電極23形成於與液晶晶胞2重疊時位在與顯 示像素電極10之非形成領域一致之部位。 接著，使用氧電漿氧化陽極22之表面。然後，如第4D 圖所示般於陽極22上藉蒸鍍法形成有機£1^層25以覆蓋絕緣 膜24及輔助電極23。其中，由陽極22側蒸鑛2TNATA作為電 15洞注入層，蒸鑛α-NPD作為電洞輸送層，且蒸鍛Alq作為 發光層，形成3層結構之有機£1^層25。接著，於有機£1^層 25上再分別瘵鍍LiF厚度〇.5nm，A1厚度2〇〇nm，藉此形成陰 極26 〇 接著，如第4E圖所示，使用黏貼有由氧化把等構成之 吸濕材27之密封板28，並於乾燥氮氣環境下使用環氧樹脂 系黏著劑黏接第3玻璃基板21與密封板烈藉此密封。如前 述，完成本實施形態之用以作為背光之有機EL照明裝置3。 該有機EL照明裝置3係發綠色光。 液晶晶胞2係藉公知之方法製造。例如，於由玻璃等構 1251700 成之第1透明基板13表面形成多數由ITO等構成之條紋狀之 透明電極11之圖案後，再形成配向膜12使其覆蓋透明電極 11，且於由玻璃等構成之第2透明基板16表面形成多數與由 ΙΤΟ等構成之透明電極11垂直之條紋狀之透明電極14後，形 5 成配向膜15使其覆蓋透明電極14。 接著，如第4F圖所示，使第1及第2透明基板13、16配 置成隔著用以控制注入之液晶之膜厚之分隔物貼合，使透 明電極11與透明電極14垂直並對向，並於其内部注入液晶 來形成液晶17。最後，於第丨及第2透明基板13、16之裡面 10形成偏光板19。如圖中之圓C所示，互相垂直之條紋狀 之透明電極11、14所重疊之部分構成顯示像素電極1〇。 接著，將液晶晶胞2與有機EL照明裝置3重疊並固定， 使液晶晶胞2之偏光板18與有機EL照明裝置3之第3透明基 板21對向，且使袼子狀之輔助電極23與顯示像素電極⑺之 15非形成領域之配置成矩形之顯示像素電極1〇間位置一致， 完成液晶顯示裝置i。為了確實進行該重疊步驟，係以於液 晶晶胞2及有機EL照明裝置3之各個適當之部位設有對位標 誌為佳。 20 如、上之w兒明，由於本實施形態事先於透明電極之陽 和上又有由孟屬材料構成之輔助電極23，因此可降低陽 極22之電阻值，可防止電料低造成之發光不均或發哉， 而實現可完整地均-發叙可靠性高之用以作為背光之有 機EL照明裝置3。 另 w ，由於輔助電極23設置於液晶晶胞2之 顯示像素電極10之非 非形成項域，因此，可防止因輔助電極 15 1251700 23遮光造成有機EL照明裝置3亮度降低之問題。且，由於在 輔助電極23上形成有絕緣膜24，因此，有機EI^|25之輔助 電極23遮光之部位沒有電流流動，可實現有機£1^照明裝置 之低消耗電力。且，藉由形成絕緣膜，可防止輔助電極 5之平坦性不良所造成之輔助電極23與陰極26之短路或漏電 流之問題。依據前述，可實現具有可靠性高、可完整地均 一發光之低消耗電力之有機EL照明裝置之液晶顯示裝置。 第1實施形態之變形例 以下’針對第1實施形態之變形例進行說明。該變形例 10中，液晶顯示裝置之有機EL照明裝置之結構與第i實施形態 有些許不同。此外，將與第1實施形態之液晶顯示裝置相同 之構成構件等附上同一標號並省略說明。 (液晶顯示裝置之結構） 第5圖係顯示本變形例之液晶顯示裝置之構成要素之 15有機EL照明裝置之結構之概略截面圖。 本變形例之液晶顯示裝置（第6G圖所顯示之液晶顯示

25及金屬電極之陰極26以覆蓋絕緣膜幻，並於陰極％上方 隔著由氧化鈀等構成之吸濕材27設置密封板28 ，再藉不圖 16 1251700 示之黏著劑固定密封板28而構成。 絕緣膜43係以氧化石夕等絕緣性無機材料或聚酿亞胺等 感光性樹脂材料作為材料，於此係以前者作為材料，並以 仿照輔助電極23之形狀形成為覆蓋辅助電極23之上面， 5又，藉該絕緣膜24分隔輔助電極23與有機虹層25，使輔助 電極23與有機EL層25絕緣。 如本變形例般形成絕緣膜43使其覆蓋辅助電極23之表 面全體，使輔助電極23與有機此層25絕緣，藉此可使有機 EL照明褒置42之發光效率提昇。且，形成絕緣膜43使其覆 H)蓋輔助電極23之表面全體，藉此辅助電肋與陰極％之間 由絕緣膜43分隔並確實地絕緣，可防止前述短路或漏電流。 (液晶顯示裝置之製造方法） 第6A圖〜第6G圖係依照步驟順序顯示前述本變形例之 液晶顯示裝置之製造方法之概略截面圖。於此，主要係針 Μ對本變形例之液晶顯示裝置之主要結構之有機虹照明裝置 之製造步驟作說明。 百先’如第6A圖所示般，由玻璃等構成之第3透明基板 21上形成由IT〇等構成之陽極22,並於陽極^上形成例如鋁 (Α1)膜31之膜作為電極材料。 2〇才妾著’如第6Β圖所示般使Α1膜31形成電極形狀，並形 成輔助電極23之圖案。此時，輔助電極_成為於與液晶 晶胞2重疊時位在與顯示像素電極1〇之非形成領域一致之 部位。 接著’如第6C圖所示般，於陽極22上形成絕緣性無機 17 12517〇〇 材料之氧切膜44使其覆蓋輔助電極23。 然後，如第6D圖所示般使氧化石夕膜44仿照輔助電極23 之形狀成形，並形成覆蓋辅助電極η之表面全體之 43之圖案。 接著使用氧電漿氧化陽極22之表面。接著，如第6E 圖所丁般於陽極22上藉黎鑛法成膜有機虹層使其覆蓋絕 緣膜43。其中，由陽極22側蒸艘2TNATA作為電洞注入層， 蒸鍍α.作為電洞輸送層，且蒸鑛蝴作為發光層，形 幻層結構之有機紅層25。接著，於有機EL層25上再分別 « ,、、、鑛LiF厚度G.5nm ’ A1厚度2()()nm，藉此形成陰極％。 接著’如第6F圖所示般使用貼附有由氧化把等構成之 吸邊材27之被封板28 ’並於乾燥氮氣環境下使用環氧樹脂 系、黏著劑黏著第3玻璃基板21與密封⑽，藉此進行密封。 如此一來，完成本變形例之用以作為背光之有機el照明裝 15置42。該有機EL照明裝置42發綠光。 液晶晶胞2係藉公知之方法製造。例如，於由玻璃等構 成之第1透明基板13表面形成多數由IT〇等構成之條紋狀之 鲁 透明電極11之圖案後，再形成配向膜12使其覆蓋透明電極 11 ’且於由玻璃等構成之第2透明基板16表面形成多數與由 2〇 ΙΤ〇等構成之透明電極11垂直之條紋狀之透明電極14後，形 成配向膜15使其覆蓋透明電極14。 接著，如第6G圖所示，使第丨及第2透明基板13、16配 製成隔著用以控制注入之液晶之膜厚之分隔物貼合，使透 明電極11與透明電極14垂直並對向，並於其内部注入液晶 18 1251700 來形成液晶17。最後，於第1及第2透明基板13、16之裡面 形成偏光板18' 19。如圖中之圓c所示，互相垂直之條紋狀

10 設有對位標認為佳。 15 20 如以上之說明’由於本實施形態事先於透明電極之陽 極22上設有由金屬材料構成之輔助電肋，因此可降低陽 極22之電阻值 可防止電壓降低所造成之發光不均或發 ”、、而貝現可凡整地均一發光之可靠性高之用以作為背光 之有機EL&明裝置42。又，由於輔助電極23設置於液晶晶 胞之,、、、員示像素私極1〇之非形成領域，因此，可防止因輔助 電極23遮光造成麵扯照明裝置a亮度降低之問題。且， 由於形成有絕緣膜43使其覆蓋輔助電極23之表面全體，因 此，有機EI^25之辅助電節遮光之部位沒㈣流流動， 可實現有機EL照明裝置之低消耗電力。且，藉由形成絕緣 膜’可防止辅助電極23之平坦性不良所造成之辅助電極^ 與陰極26之短路麵電制題。依據前述，可實現具有可 靠性高、可完整地均—發光之低雜電力之有機EL照明裝 置之液晶顯不裝置。 19 1251700 第2實施形態 以下，針對本發明之第2實施形態進行說明。本實施形 悲中，液晶顯示裝置之有機EL照明裝置之結構與第丨實施形 怨有些許不同。此外，將與第1實施形態之液晶顯示裝置相 5同之構成構件等附上同-標號並省略說明。 (液晶顯示裝置之結構） 第7圖係顯示本實施形態之液晶顯示裝置之構成要素 之有機EL照明裝置之結構之概略截面圖。 本實施形態之液晶顯示裝置（第8G圖所顯示之液晶顯

Field of the Invention The present invention relates to a liquid crystal display device using a so-called organic illuminating device as a backlight of a liquid crystal cell and a method of manufacturing the same. BACKGROUND OF THE INVENTION The liquid crystal display device is used in a screen or a notebook computer, a mobile phone, a television, etc., and is widely used as a representative of a flat panel display. Since the liquid crystal cell H) is a non-emission type element which does not emit light, a light source called a backlight which can be irradiated from the back surface of the liquid crystal cell is usually required. In general, the most commonly used one is a light guide body composed of a light guide tube and a light guide body that emits light from a fluorescent tube as a surface light source. However, since the light guide body method requires a thickness to the extent of uniform surface light emission (about 3 times as large as that of the liquid crystal cell), it is difficult to make the thickness of the entire liquid crystal display device thin. Therefore, in recent years, attempts have been made to use a surface light-emitting element light source as a backlight. In particular, the surface light-emitting element has an organic EL illumination device composed of a timing EL element, and since it can be very thin, it has the strength as a backlight of a liquid crystal display device. The 20 帛9 diagram shows a schematic cross-sectional view of a conventional organic EL illumination. In the organic EL illumination device, an anode 102 made of a transparent electrode such as ITO is formed on a transparent substrate 1〇1 made of glass or the like, and an organic EL layer containing an organic light-emitting body is sequentially laminated thereon, and Li, Mg, a work function such as 1251700, a cathode made of a small metal, and in order to block external air such as moisture or oxygen, the sealing plate 1〇5 made of glass or the like is adhered and sealed in a dry nitrogen atmosphere using an adhesive 106. The substrate 1〇1. When the organic EL illumination device as described above is used as the backlight of the liquid crystal display device, the backlight can be thinned, and the thickness of the entire liquid crystal display device 5 can be also fixed. However, in recent years, the demand for a larger area of a liquid crystal display device has increased, and the organic EL illumination device for light has to be enlarged. However, with the large area of the organic EL illumination device, the influence of the electrode impedance cannot be ignored. In particular, a non-metallic material such as a tantalum crucible used for a transparent electrode of an anode has a low electrical resistivity of 10, and therefore, the influence of a voltage drop is large, and there is a problem that an organic EL illumination device forms uneven light emission or heat generation in a transparent electrode increases. In order to solve the aforementioned problems, it is necessary to lower the resistance value of the transparent electrode. Therefore, there is a technique of using a low-resistance auxiliary electrode made of a metal to reduce the resistance of the transparent electrode as disclosed in Patent Document 1. However, since the metal 15 is opaque in the visible light region, the auxiliary electrode portion shields the light emitted from the organic EL illumination device to lower the luminance. A method for solving the problem as a problem is disclosed in Patent Document 2. This method is applied to a portion other than the field in which the display pixel electrode of the liquid crystal display device is formed, that is, an auxiliary electrode is provided which does not directly affect the display. According to this configuration, since the liquid crystal display device is originally provided with the auxiliary electrode in the portion where the light is not permeable, the liquid crystal display device as a whole substantially solves the problem of the brightness reduction caused by the shading of the auxiliary electrode. However, even in the structure disclosed in Patent Document 2, current flows in the organic EL layer in the opaque portion on the auxiliary electrode, which lowers the luminous efficiency of the organic 1251700 EL illumination device. Further, since the surface of the metal material is flat through the parent ITO, the short circuit between the auxiliary electrode and the cathode or the leakage current between the two causes a leakage current. Patent Document 1 Patent Publication No. PCT No. 268 982 5 Patent Document 2 Patent Publication No. 2002-156633 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a grade rate of a lift EL illumination device. And a low-consumption power=liquid crystal display device having an organic rainbow illumination device capable of preventing a galvanic susceptibility of a galvanic electrode and a second electric ray to generate a short circuit or a leakage current, and which can completely uniformly emit light, and a method of manufacturing the same.

The liquid crystal display device of the present embodiment is as shown in FIG. 1C. a liquid crystal cell 2 having a display mechanism as shown, and a 20-electrode EL illumination device 3 for use as a backlight of the liquid crystal cell 2. The liquid crystal cell 2 includes a first transparent substrate 13, a second transparent substrate 16, and The liquid crystal layer 17. The first transparent substrate 13 is made of glass or the like, and has a stripe-shaped transparent electrode 11 made of ruthenium or the like on the surface, and an alignment film 12 is formed on the transparent electrode 11. The second transparent substrate 16 is made of glass or the like, and 1251700 is formed with a plurality of strips perpendicular to the transparent electrode u made of ITO or the like, and a transparent electrode 14 having a pattern, and an alignment film 15 is formed on the transparent electrode 14.

Further, a polarizing plate 18 is disposed on the inside of the first transparent substrate 13, and polarized light is disposed inside the second transparent substrate 16. The liquid crystal cell 2 is formed by forming a matrix by the liquid crystal layer 17 or the like interposed therebetween by the transparent electrode 11 and the transparent f-pole 14 as shown in FIG. 8 and FIG. 1B. The portion of the shape constitutes a plurality of display pixel electrodes (10) mouth portion 1 〇 10 15 20 In addition, the liquid sa unit cell is simply described in a matrix type herein, but the structure of the present invention can also be applied to a pixel portion provided with a thin film transistor. (tft) An active matrix type liquid crystal cell of a conversion element. The organic illuminating device 3 has a structure in which an anode 22 of a transparent electrode made of IT 〇 or the like is formed on the surface of the third transparent substrate 21 made of glass or the like as shown in Fig. 2, and the (four) pole 22 is shaped by a power-saving device. (4) a pattern, and an insulating film 24 is formed to cover the auxiliary electrode 2, and the organic EL layer 25 and the cathode % of the metal electrode are sequentially formed on the anode 22 to cover the auxiliary electrode and the barrier film 24'. Above the cathode 26, a seesaw 28 is disposed via a (four) she-like structured absorbent material 27, and the sealing plate is fixed by an adhesive (not shown). The auxiliary electrode 23 is disposed in a field other than the display pixel electrode 1 ,, in other words, a part of the non-formation field of the display pixel electric coffee, and the display pixel electrode arranged in a rectangular shape as shown in the first figure of the niece. 1 set in a grid shape, and use metal such as Ming or silver, wire, and enamel as material. The material of the machine or the stellate film of the styrofoam is made of a material such as yttrium oxide or the like, which is made of a material such as yttrium oxide, and the like. The shape is formed to cover the upper surface of the auxiliary electrode, and the upper surface of the auxiliary electrode 23 and the organic rainbow layer 25 are separated by the insulating film 24, and the auxiliary electrode 23 and the organic layer 25 are insulated from the upper side of the auxiliary electrode 23. The figure is a schematic cross-sectional view showing the structure of a comparative example (conventional example) used as a backlight of a liquid crystal display device. The example of Fig. 3 does not have an insulating film 24 as in the present embodiment. The organic (10) 25 is directly formed to cover the auxiliary electrode 23. Since the organic EL layer 25 is applied with a voltage between the anode 22 and the cathode %, the upper surface of the auxiliary electrode 23 in FIG. 3 is organic. The conduction between the layer and the cathode 26 is mainly caused by a decrease in the luminous efficiency of the organic EL illumination device 3. Therefore, as in the present embodiment, the insulating film 24 is formed on the upper surface of the auxiliary electrode 以 so that the upper surface of the auxiliary electrode 23 is organic EIJ|2y€ edge, thereby improving the luminous efficiency of the organic EL illumination device 3. 15 Moreover, in the case of Fig. 3, the poor flatness of the metal material may cause a short circuit between the auxiliary electrode 23 and the cathode 26 or In the present embodiment, the insulating film 24 is formed on the upper surface of the auxiliary electrode 23, whereby the auxiliary electrode is reliably insulated from the cathode 26 by the insulating film 24, thereby preventing the short circuit or leakage current. From the anode 22 side, the two-layer structure of the hole transport layer/organic light-emitting layer, or the three-layer structure of the hole transport layer/organic light-emitting layer/electron transport layer, or the hole injection layer/hole transport layer/organic light emission a four-layer structure of a layer/electron transfer layer, etc. For example, there is a two-layer structure in which a-NpD is used as a hole transport layer and Alq is used as an organic light-emitting layer. The 121251700 component of the structure is paid to green. A dopant for emitting various luminescent colors, in addition, by adding an organic EL element having a plurality of luminescent colors to the organic light-emitting layer, the luminescent layer of the organic light-emitting layer is added, and the doping is performed. 'Or a layer of dopants that emit R, G, and B light, respectively, to obtain an organic EL element that emits white light. The cathode 26 is used to efficiently inject electrons into the organic layer 25, with a small work function. It is necessary to use metals and fluorinated alkali metal compounds as materials for the metal, and the metal with a small work function such as metal is unstable. Therefore, in order to stabilize, it is necessary to use stable metals such as Ming or silver. For example, use Ming Clock σ m, fluorinated clock /! g2 layer structure as cathode The sealing plate 28 is made of glass or the like, and in order to prevent the _L layer 25 from being isolated from the outside air, it is adhered to and sealed to the third transparent substrate 21 by, for example, an epoxy tree (4) adhesive under a nitrogen atmosphere. 20, as shown in FIG. 1C, the liquid crystal cell 2 and the organic EL illumination device 3' overlap the polarizing plate 18 of the liquid crystal cell 2 with the third transparent substrate 21 of the organic EL illumination device 3, and as shown in FIG. In the first embodiment, the display pixels arranged in a matrix form in the non-formation field of the display pixel electrode 10 are electrically connected to each other to form a liquid crystal display device 1. (Manufacturing Method of Liquid Crystal Display Panel) FIG. 4A and FIG. 4F are schematic cross-sectional views showing a method of manufacturing the liquid crystal display device of the present embodiment in order of steps. Herein, the manufacturing steps of the organic EL lighting device 13 1251700, which is the main structure of the liquid crystal display device of the present invention, are mainly explained. First, as shown in FIG. 4A, an anode 22 made of πτο or the like is formed on the third transparent substrate 21 made of glass or the like, and an aluminum (A1) film 31 is formed as an electrode material on the anode 22, and then coated. A film of polyacrylic acid 5 imine 32 of a photosensitive resin material. Next, the polyimide film 32 is exposed and developed by lithography as shown in Fig. 4B, and the polyimide film 32 is processed to form a pattern of the insulating film 24. Next, as shown in Fig. 4C, the octagonal film 31 is dried with the insulating film 24 as a mask, whereby the auxiliary electrode 23 which is shaped like the insulating film 24 is formed. At this time, the auxiliary electrode 23 is formed at a portion which coincides with the non-formation region of the display pixel electrode 10 when it overlaps with the liquid crystal cell 2. Next, the surface of the anode 22 is oxidized using an oxygen plasma. Then, as shown in Fig. 4D, an organic layer 25 is formed on the anode 22 by vapor deposition to cover the insulating film 24 and the auxiliary electrode 23. Among them, the 2TNATA from the anode 22 side is used as the electric 15 hole injection layer, the vaporized α-NPD is used as the hole transport layer, and the Alq is steamed and forged as the light-emitting layer to form the organic layer 1 of the 3-layer structure. Next, on the organic layer 1 25, the thickness of the LiF is further plated. 5 nm, A1 has a thickness of 2 〇〇 nm, thereby forming a cathode 26. Next, as shown in Fig. 4E, a sealing plate 28 to which a moisture absorbing material 27 composed of an oxidizing material or the like is adhered is used, and a ring is used in a dry nitrogen atmosphere. The oxygen resin-based adhesive adheres to the third glass substrate 21 and the sealing plate to thereby seal. As described above, the organic EL illumination device 3 used as the backlight of the present embodiment is completed. The organic EL illumination device 3 emits green light. The liquid crystal cell 2 is produced by a known method. For example, a pattern of a plurality of stripe-shaped transparent electrodes 11 made of ITO or the like is formed on the surface of the first transparent substrate 13 made of glass or the like 1251700, and then the alignment film 12 is formed to cover the transparent electrode 11 and is made of glass or the like. On the surface of the second transparent substrate 16 which is formed, a plurality of stripe-shaped transparent electrodes 14 which are perpendicular to the transparent electrode 11 made of ruthenium or the like are formed, and then the alignment film 15 is formed to cover the transparent electrode 14. Next, as shown in FIG. 4F, the first and second transparent substrates 13 and 16 are placed so as to be bonded to each other via a separator for controlling the thickness of the liquid crystal to be injected, and the transparent electrode 11 and the transparent electrode 14 are perpendicular to each other. The liquid crystal 17 is formed by injecting liquid crystal into the inside thereof. Finally, a polarizing plate 19 is formed on the inner faces 10 of the second and second transparent substrates 13, 16. As shown by the circle C in the figure, the portions of the strip-shaped transparent electrodes 11, 14 which are perpendicular to each other overlap each other to constitute the display pixel electrode 1''. Then, the liquid crystal cell 2 is superimposed and fixed to the organic EL illumination device 3, and the polarizing plate 18 of the liquid crystal cell 2 is opposed to the third transparent substrate 21 of the organic EL illumination device 3, and the auxiliary electrode 23 of the braid shape is formed. The position of the display pixel electrode 1 arranged in a rectangular shape in the non-formation field of the display pixel electrode (7) is the same, and the liquid crystal display device i is completed. In order to surely perform the overlapping step, it is preferable to provide a registration mark at each appropriate portion of the liquid crystal cell 2 and the organic EL illumination device 3. For example, in the present embodiment, since the auxiliary electrode 23 composed of a genus material is added to the yang of the transparent electrode in advance, the resistance value of the anode 22 can be reduced, and the luminescence caused by the low electric material can be prevented. The organic EL illumination device 3 used as a backlight can be realized with a high degree of uniformity and uniformity. Further, since the auxiliary electrode 23 is provided in the non-formation domain of the display pixel electrode 10 of the liquid crystal cell 2, the problem that the luminance of the organic EL illumination device 3 is lowered due to the light shielding of the auxiliary electrode 15 1251700 23 can be prevented. Further, since the insulating film 24 is formed on the auxiliary electrode 23, no current flows in the portion where the auxiliary electrode 23 of the organic EI^|25 is shielded, and the low power consumption of the organic illuminating device can be realized. Further, by forming the insulating film, it is possible to prevent the short circuit or the leakage current of the auxiliary electrode 23 and the cathode 26 caused by the poor flatness of the auxiliary electrode 5. According to the foregoing, it is possible to realize a liquid crystal display device having an organic EL illumination device having high reliability and low power consumption which can completely emit light uniformly. Modification of the first embodiment Hereinafter, a modification of the first embodiment will be described. In the modification 10, the configuration of the organic EL illumination device of the liquid crystal display device is somewhat different from that of the i-th embodiment. In addition, the same components as those of the liquid crystal display device of the first embodiment are denoted by the same reference numerals, and their description is omitted. (Structure of Liquid Crystal Display Device) Fig. 5 is a schematic cross-sectional view showing the configuration of the organic EL illumination device of the components of the liquid crystal display device of the present modification. The liquid crystal display device of the present modification (the liquid crystal display device 41 shown in FIG. 6G) includes a liquid crystal cell 2 of the liquid crystal cell which is the same as that of the first embodiment, and is used as the organic EL illumination of the backlight of the liquid crystal cell 2. Device 42. The organic EL illumination device 42 is formed on the surface of the third transparent substrate 20 21 made of glass or the like to form an anode 22 of a transparent electrode made of ITO, and forms a pattern of the auxiliary electrode 23 on the anode 22, and forms an insulation. The film is made to cover the entire surface of the auxiliary electrode 23, and an organic layer 125 and a cathode 26 of the metal electrode are sequentially formed on the anode 22 to cover the insulating film, and the palladium oxide is formed over the cathode. The moisture absorbing material 27 is provided with a sealing plate 28, and is constructed by fixing the sealing plate 28 with the adhesive shown in Fig. 16 1251700. The insulating film 43 is made of an insulating inorganic material such as oxidized oxidized stone or a photosensitive resin material such as polyacrylonitrile. The former is used as a material, and is formed to cover the upper surface of the auxiliary electrode 23 in a shape similar to the auxiliary electrode 23.
